DISK-CUTTING MACHINE.

Specification of Letters Patent.

Patented Dec. 27, 1921.

Application led August 6, 1921. Serial No. 490,288.

To all whom it may concern:

Be it known that we, FRANK BLANDO and SANTE` DUCA citizens of the UnitedStates, residing at ew York, in the county and State of New York, haveinvented certain new and useful Improvements in Disk- Cutting Machines,of which the following is a full, clear, and exact specification.

This invention relates to apparatus for cutting disks or wafers ofaltar-bread, but may be used for cutting thin disks of other material,and has for its object to provide improved means for cutting said disksand for discharging them from the cutter after the have been formed.

'lyhe invention contemplates the provision of a cylindrical cutter whichmay be rotated continuously by an electric motor, or other source ofpower, and which Inay be periodically lowered and raised foraccomplishing the cutting operation without interrupting the rotarymovement of the same. The cutter is provided with means for pressingrthe sheet of bread into contact with a supporting table during thecutting operation, said pressing means being yieldingly carried inadvance of the cutter so as to engage said sheetprior to the contact ofthe cutter therewith.

The table, for supporting the sheet of bread, is provided with a movablesection below the cutter, and means for lowering said movable section todischarge the cut disk, after downward movementvof the cutter, isoperated by the same power that rotates and reciprocates said cutter.This movable section of the table is renewable so that when one becomesworn by continued contact of the cutter therewith, it may be replaced bya new piece. Said movable section may also be interchanged with anotherone of different size to accommodate different sizedv cutters, it beingthe practice to form the disks or wafers of altar-bread in one size forthe use of the priests and in a smaller size to be distributed to thecongregation. y

The invention will be further hereinafter described in connection withthe accompanying drawings, which constitute part of this specification,and then more specifically defined 4in the claims at the end of thedescription.

In the drawings, 1 indicates a supporting frame having a top plate 2 andcross piece 3 below said plate for supporting an electric motor 4, whichis connected by a belt 5 with a sheave 6 on a shaft 7 suitably journaledon the frame 1 at one side thereof and below the plate 2. Standards 8rise from the plate 2 for supporting the main shaft 9 above and at therear of said plate, and said shaft 9 is operatively connected to theshaft 7 by a sprocket chain 10, whereby said main shaft Mounted on theplate 2 of the frame 1 and.

spaced above the same by blocks 12 is a removable table comprising twosections 13 and 14 which meet along their inner edges, as at 15, and aresecured in place by a bolt' 16 extending upwardly from the plate 2 andfitted with a wing nut 17 and a iianged washer plate 18 engagingupstanding franges 19 and 20, respectively, on the meeting edges of thetable sections 13 and 14. The flanges 19 Aand 2() may be spaced slightlyapart, as best shown in Fig. 4, to allow the bolt 16 to extend betweenthem, and said flanges may be extended along the rear edges of the tablesections which are preferably cut away, as at 21, Fig. 4. The tablesections may also be secured to the plate 2 of the supporting frame 1 bymeans of sliding latches 22, best shown in Figs. 8 and 9, one of saidlatches being preferably adapted to engage each of the front cornerportions of said plate. r1`hese latches are fitted to slide in notches23 in the under faces of certain of the blocks 12, and have elongatedslots 24 through which the heads of screws 25 extend, so that thesliding movement of the latch is limited by the engagement of said screwheads with the ends of said slots. Each latch has a portion folded uponitself for gripping the edge of the plate 2, and the extremity 26 ofsaid folded portion is preferably bent or curved away from the plate, asclearly shown in Fig. 8, to provide a finger grip for actuating thelatch and also for guiding said latch over the edge 0f the plate 2.

r)The table section 13 is preferably provided with a folding leaf 27hinged thereto at 28 and having a folding brace 29 pivoted to the underside of the leaf at 30 and provided with a notch 31 at its lower end toengage a cross bar 32 of the frame 1, as best shown in Fig. 1. lhen theleaf 27 is to be folded, the brace 29 is disengaged from the cross bar32, as will be readily understood.

Extending from the plate 2 upwardly between the meeting edges of thetable sections 13 and 14 are two standards 33 and 34 spaced one behindthe other, as best shown in Figs. 2 and 4. To the upper end of the rearstandard 34 a lever 35 is intermediatcly pivoted at 36, while theforward end of said lever is pivoted at 37 to a link 38, in turn pivotedt0 a vertical slide 39 fitted in the standard' 33 which is tubular inform and has a vertical slot 40 through which extends an arm 41 fixed tothe vertical slide 39, said arm carrying the cutter and presser-foot,which will be hereinafter described. The rear end of the lever 35carries a roller 42 which is held down in engagement with a cam 43 by aspring 44 connected to the lever at 45 and to the standard 34 at 46. Thecam is mounted on theJ main shaft 9, as clearly shown in Figs. 1. 2, 3and 5, and is of such shape as to periodically rock the lever 35 formoving the slide 39 and its arm 41 vertically in the standard 33. l

Vertically adjustable in the outer end of the arm 41 is a hollow screw47 having a hand wheel 48 fixed to its upper end in any suitable manner,as by having an intcrnally7 screw-threaded socket 49 engaging the upperend of the screw 47, and a set screw '30 carried by said hand wheel andextending into a longitudinal slot 51 in said screw. Two of the slots 51are preferably provided at diametrically opposite points on the screws47, and said slots extend down for a considerable distance from theupper end of the screw. Into said slots extend lugs 52 projectingradially from a cylindrical nut 53 mounted to slide axially in thehollow screw 47. A spring- 54 is arranged in the upper end portion ofsaid screw between the hand wheel 48 and the cylindrical nut 53 foryieldingly pressing said nut downwardly with its projecting lugs 52engaging the lower end of the slots 51. A rod 55 extends upwardlythrough the hollow screw 47 and has its upper end portion 56 threaded toadjustably fit in the cylindrical nut 53, see Figs. 11 and 12. The upperextremity of said rod projects through the cylindrical nut and carries aring 57, or other suitable obstruction therein, to prevent the rod frombeing turned downwardly out of the nut.

The lower end portion of the rod 55 projects from the screw 47 and isguided in a plug 58 fitted in the lower end of said screw and retainedin place by a set screw 59. The lower end of rod 55 is squared at 60 tofit in a similar] shaped socket 61 in a presser-foot 62 w )ich isdetachably secured to said rod by means of a. transverse screw 63, Fig.11. Said presser-foot is preferably covered with cloth 64, the edges ofthe cloth being gathered around the shank of the presser-foot andsecured thereto by one or more wrappings of cord 65. The gathered edgesof the cloth and the cord securing the same, are covered by a flaredcollar 66 fitting around the shank of the presser-foot and secured inplace by the screw 63 which detachably fastens said presser-foot to therod 55.

The plug 58 extends annularly beyond the lower end of the screw 47forming a supporting ledge 67 for a horizontal gear 68 which is mountedto rotate about the cylindrical lower end portion 69 of said screw 47.Ball bearings 70 are interposed between the ledge 67 and the hub 71 ofthe gear 68, and said gear is yieldingly held down upon said ballbearings 70 by a spring 72 coiled about the cylindrical portion 69 ofthe screw 47, and extending between a collar 7 3 mounted around saidscrew, and ball bearings 74 placed above said gear 68.`

A cylindrical cutter 75 may be detachably connected to the hub 71 of thegear 68 by means of a lug 76 Vand a screw 77 projecting from said hub atdiametrcally opposite points to engage axially extending notches 78 and79, respectively, in the upper end of said cutter. When the screw 77 isloosened, -the cutter 75 may be readily slipped off of the hub 71, andwhen said cutter has its notches engaged with said lug and screw, asillustrated in Fig. 11, the tightening of said screw will retain thecutter in place. The gear 68 is provided with a segmental annular flange80 depending therefrom eccentrically of the hub 7l, and carrying a lug81 and screw 82 at diametrically opposite points for detachably securinga larger cylindrical cutter 83 to said rear, as shown in Fig. 20. Asillustrated in Fig. 11, when the smaller cylindrical cutter 75 is used,the presser-foot 62, associated therewith, is of slightly less diameterthan the cutting edge of said cutter. When the larger cylindrical cutter83 is employed for cutting disks of larger size for use by the priests,a larger presser-foot 84, Figs. 20 and 23, is employed, the same beingconstructed and detachably fastened to the rod 55 in the same manner asalready described in connection with the presser-foot 62.

It will be noted that the screw 47 may be bodily adjusted vertically onthe arm 41 for bringing the resser-foot and cutter nearer to or fartherrom the table. To retain said screw in adjust-ed position, one or morevertically sliding bolts 85 are mounted on said arm to engage an annularseries of sockets.

86 in the under face of the hand wheel 48. Two bolts 85 are indicated inFig. 14, and they are guided in pairs of lugs 87 at opposite sides ofthe arm 41, but only one of said bolts need be long enough to engage thesockets 86 in the hand wheel 48. The lower ends of the bolts 85 areconnected by a cross piece 88 having projecting end portions 89 servingas finger' pieces for withdrawing the bolts 85 from the hand wheel 48when the latter is to be rotated in order to vertically adjust the screw47. A spring 90, connected to the arm 41 and to said cross piece 88,serves to yieldingly hold the bolts 85 in engagement with the handwheel.

A beveled gear 9 1 is mounted on the main shaft 9 and meshes with asimilar pinion 92 on the upper end of a vertical shaft 93, suitablyjournaled at its upper end in a cross piece 94 extending betweenadjacent standards 8, as best shown in Fig. 1. The lower end of saidvertical shaft 93 is journaled at 95 in a strip 96 extending diagonallyacross the plate 2 on the supporting frame 1 and suitably fastenedthereto. A horizontal shaft 97 is journaled in upstanding lugs 98 on thestrip 96 and carries beveled pinions 99 and 100 on its opposite ends.The pinion 99 meshes with a beveled gear 101 on the lower end of thevertical shaft 98, while the pinion 100 meshes with a beveled pinion 102on the lower end portion of another' vertical shaft 108 which is alsoournaled at its lower end in the strip 96, as at 104. The vertical shaft108 has its upper end journaled in a bracket 105, which may bedetachably fastened to the standard 88, indicated in Fig. 22, and saidshaft carries an elongated gear 106 fast thereon and meshing with thegear 68, which carries the cutter.

`It will be noted from the foregoing description that as long the mainshaft 9 is turned, said elongated gear 106 will be continuously rotatedthrough the vertical shaft 93, horizontal shaft 97, and vertical shaft1.08, and their intermeshing beveled gears or pinions, and that thecutter-carrying gear 68 will also be continuously rotated because it isin constant mesh with said elongated gear. It will further be noted thatduring each rotation of the main shaft 9 the arm 41 and screw 47carrying the gear 68 will be reciprocated by the cam 48 acting upon thelever 85, as already described. The cutter is thus given a combinedrotary and reciproeating movement, the former of which is con` tinuous,while the latter is periodical.

In the table section 18 an opening 107 is formed below the cutter, andin said opening a frame 108 is removably supported upon diagonallyarranged metal strips 109 secured to the under surface of said tablesection and extending across the corners of the opening 107, as shown inFigs. 4 and 18. Said frame 108 is designed to lit closely in the opening107, so that it will be retained therein during the operation of themachine by frictional contact with the margins of said opening. In saidframe 108 there is an opening 110 in which a trap door or block 111 isfitted, the same being preferably previded with a beveled forward end112 litting a correspondingly shaped front edge portion of the opening110 in the frame.

In the operation of the machine, the cylindrical cutter operates on theblock 111, and' in order to effectively discharge the cut disks, saidblock or trap door is adapted to be periodically lowered, as indicatedin dotted lines in Fig. 10. This periodical movement of the trap door isaffected by a toggle 112, the upper link of which is pivotally connectedat 118 to a plate 114 hinged at 115 to a bracket 116 suitably secured tothe plate 2, said trap door being mounted on the plate 114, as will behereinafter explained more in detail. The lower link of the toggle ispivotally connected at 117 to a lower portion 118 of the bracket 116,and said upper and lower links are pivotally connected to each other at119. When the toggle is extended, as shown in solid lines in Fig. 10,the trap door or block 111 is supported on a level with the frame 108and the table section 18, but when said toggle is broken er collapsed,as indicated in dotted lines in the same figure, the trap door will belowered and its free end will come in contact with a buffer 120, ofrubber or other suitable material, mounted on the lower portion 118 ofthe bracket 116. A vertical shoulder or abutment 121 is formed on saidlower portion of the bracket to limit the movement of the toggle to avertical position when it is being extended. The lower link of thetoggle is provided with an offset 122 in the direction of its foldingmovement, and into said offset, which is perforated for that purpose,one end of a lever 128 loosely extends, as best shown in Fig. 21.

Said lever 128 is intermediately pivoted at 124 to an inclined bracket125 suitably secured to the plate 2 below the table, and the other endof the lever is pivotally connected at 126 to a connecting rod 127attached at its rear end to one extremity of a segmental rocker member128 journaled in a bracket 129 on the plate 2 at a point near the rearedge of the table and almost directly below a cam 180 on the main shalt9. The other extremity of the rocker niember 128 is connected by a link181 to a lvertical push rod 182 which guided in straps 188 on one of thestandards 8 and has a roller 184 at its upper end to engage said cam180. The push rod 182 is yieldingly f raised to hold said roller 1214constantly in engagement with the cam 180 ly springs 185, connected attheir upper ends to the upper strap 188, and at their lower ends to acollar 180 suitably clamped around said push rod.

rlhe relative shapes of the cams 180 and 48 are such as to cause thedropping of the trap door 111 through the action of the push rod 182,lilik 181, rocker member 128, cennecting rod 127, lever 128 and toggle112, as soon as a disk has been severed hy the cutter and before saidcutter is raised out of Contact with said trap doei'. .lt will be notedthat the presseihfoot normally projects slightly below the cutter, sothat when the cutter-carrying screw 47 is lowered through the action ofthe cam .18 and associated mechanism, said presser-foot will come incontact with a sheet of altar bread (not shown) before the cutter, andthat said sheet of bread will consequently be held in contact with theupper surface of the trapdoor 111 by the compressed spring .'14 whilethe cutter is moved into contact with the bread and cuts through thesame to form a disk. When the disk has been completelyv severed, thetrap-door is droilnied, as already explained, and the compressedv spring54 then expands and again projects the presser foot below the cutter,thereby positively separating the cut disk from the sheet of bread, andinsuring the discharge of said disk as the trap-door drops. the cuttingedge of the cutter wears olf, the presser-foot may be adjusted tonormaled stand at the proper distance below the saine by turningl therod 55 in the cylindrical nut 58. The disks discharged at the periodicaldropping of the trap-door 111 fall into a container or drawer 186removably supported on ledges 187 secured to the frame 1.

Then the larger cutter 88 and larger presser-foot 84 are used, acorrespondingly larger block 188, Fig. 10, is substituted for the block111, a frame 189, having an opening 140 to lit said block 188. beingused in place of the frame 108. The blocks 111 and 188 have sockets 141in their under faces, as illustrated in Figs. 6 and 10, to lit overupwardly extending pins 142 on the hinged plate 114, so that blocks ofdifferent sizes may be readily interehanged and, when a block becomesworn from use, a, new one may be substituted therefor.

To prevent the fingers of the operator from coming below the cutter, aguard 143 is pivoted at one end to the table section 14 at 144 and isadapted to extend across the frame 108, as shown in solid lines in Fig.4. Said guard 143 may be made of rigid wire and is disposed slightlyabove the top of the table, as shown in Fig. 1. A stop 145 on the tablelimits the rearward movement of the guard, and a thumb nut 146 on thepivot pin 144 is provided for clamping said guard in operative position.When the frame 108 is to be removed, the guard may be swung out of theway, as indicated in dotted lines in Fig. 4, the thumb nut 146 beingfirst loosened. A sheet of altar bread (not shown) may be inserted belowthe guard 143, the free end of which is preferably curved upwardly, asat 147, Fig. 1, to guide the sheet below the same. Said guard not onlyprevents the fingers of the operator from getting below the cutter, butalso serves to hold the sheet of bread down upon the table during thecutting operation. At the same time, the guard does not interfere withthe slid ing of the sheet of bread over the table for feeding the samebelow the cutter.
